Top 4 Prop Bets for Dolphins vs. Chargers

The Los Angeles Chargers head to Miami in need of a rebound after dropping two straight following a 3-0 start. Injuries have gutted Jim Harbaugh’s offense, with rookie tackle Joe Alt sidelined and Justin Herbert pressured on over 40% of dropbacks the past three weeks. The Dolphins, meanwhile, enter at 1-4 and have struggled to finish drives, ranking near the bottom of the league in red-zone touchdown rate. Both teams are desperate to regain rhythm, making this matchup more unpredictable than it looks on paper.

Justin Herbert Over 1.5 Passing Touchdowns

Even with constant pressure, Herbert continues to produce through the air. He’s thrown multiple touchdowns in three of his five games this season and has averaged 196.5 yards with eight passing scores overall. Miami’s defense allows opponents to convert over 55% of red-zone trips into touchdowns — a dangerous trend against a quarterback who thrives in tight windows. The Chargers have been top-10 in play-action rate early in the season and lean heavily on the pass in goal-to-go situations. Given Miami’s struggles defending in the red zone and the Chargers’ limited rushing depth, Herbert clearing 1.5 touchdowns feels like the safest play of the four.

Quentin Johnston Over 55.5 Receiving Yards

Johnston has quietly become Herbert’s most dynamic target with 377 yards and four touchdowns through five games. Against a Dolphins secondary that has allowed 7.9 yards per attempt and ranks in the bottom third of the league in explosive pass defense, Johnston has the matchup advantage. Miami has surrendered at least one 40-yard completion in three of five games, and Los Angeles has been aggressive attacking downfield early in games. Johnston’s speed and usage in vertical routes give him a strong chance to clear 55.5 receiving yards, especially with Keenan Allen commanding attention underneath.

Tua Tagovailoa Longest Completion Under 32.5 Yards

Tagovailoa’s deep ball has regressed sharply this season, as Miami’s offense has become more horizontal than vertical. The Dolphins have only two completions over 30 yards in their past four games, and Tua’s longest completion last week was just 26 yards. Facing a Chargers defense that forces quick throws with disguised pressure looks and heavy nickel coverage, Miami will likely lean on timing routes and quick passes to move the chains. The combination of offensive inconsistency and Tua’s reduced air-yard average supports the under here.

Darren Waller to Score 2+ Touchdowns (+3000)

At +3000, this is a high-upside flier built on matchup dynamics. Miami has allowed tight ends to account for 22% of opposing teams’ red-zone targets this season — the fifth-highest rate in the league. With Herbert spreading the field horizontally due to line injuries, Waller could see mismatches inside the 20. The Chargers have lacked red-zone consistency, but against a defense that struggles with tight-end leverage and play-action coverage, Waller is a legitimate long-shot pick to find the end zone twice.

Conclusion

The Chargers’ passing game should find traction against a soft Miami defense, while the Dolphins’ big-play offense remains in flux. Herbert’s touchdown efficiency and Johnston’s growing role make Los Angeles the stronger side of the prop market this week. Miami may move the ball but lacks the vertical explosiveness to challenge deep — which makes the Tua under a smart play and Waller’s long-shot value worth a sprinkle.
